Which approach best represents a limitation of discontinuous measurement?

The approach that best represents a limitation of discontinuous measurement is that it may fail to capture the full extent of behavior. Discontinuous measurement methods, such as interval recording or momentary time sampling, only capture data during specific intervals or moments. As a result, behaviors that occur outside of these set times may not be recorded, leading to potential underrepresentation of the behavior's overall frequency or duration.

In contrast, methods that record every instance of behavior provide a more comprehensive picture, ensuring that no occurrences are missed. The ability to measure both frequency and duration is typically a strength associated with continuous measurement rather than a limitation. Similarly, real-time measurement is advantageous as it allows for immediate capturing of data without the restrictions of defined intervals or moments.
